Kuracchi (クラっち) is a junior high school student with blue hair and brownish yellow eyes. He typically wears an unzipped jacket over his formal school uniform. In his wizard form, he sports a zipped black short robe featuring blue lining underneath the jacket. During manipulation by Wanisuke, his outfit incorporates a crocodile face mask marked with the Mazica logo and the word "Croco," along with a long robe distinguished by purple lining beneath the standard short robe.

His personality is generally pleasant and gentle, though he occasionally displays rudeness. He maintains a close friendship with fellow junior high student Kezuru, whom he introduces to the "Mazica Party" card game shortly after its launch. This occurs following Kezuru’s vivid dream of wizardry and mystical creatures; Kuracchi shows him the game cards, which strikingly resemble elements from that dream.

Kuracchi exhibits enthusiasm for novel trends and stays informed about various topics. He frequently employs analytical frameworks called "Rules" to assess situations or phenomena. His name derives from the English word "scratch" (adapted into Japanese as スクラッチ or Sukuracchi), with no direct connection between this naming and his actions or abilities elaborated in the provided materials.
